无法在 CamelContext 上调用 public void org.apache.camel.cdi.CdiCamelContext.start()

Question

我正在尝试添加 CdiCamelContext 以启动路由器，如下所示。

@Inject
@ContextName("new-camelContext")
CdiCamelContext camelContext;

@PostConstruct
public void init() throws Exception {
    camelContext.addRoutes(new MyRoute());
    camelContext.start();
}

堆栈跟踪：

我需要找到一种正确的方法来使用 camel cdi 并在不同的项目中访问相同的 camel 上下文。

Answer 1

看看各种 CDI 示例

https://github.com/apache/camel/tree/master/examples

作为 Camel 2.17 的一部分，还有一个改进的 camel-cdi 组件。

http://camel.apache.org/cdi

Answer 2

@coolD，我也遇到了同样的问题，找到了解决办法。我将 Apache Camel 2.16.2 与骆驼 CDI 一起使用。我在其他 Whosebug 问题中添加了我的答案。看看吧。这可能会有所帮助。

ps。还有个骆驼2.17.0已经放出来了。我还没有尝试过。
